Self=pumping hydropneumatic vehicle spring leg with inner level regulation

摘要

The self-pumping, hydropneumatic spring leg has inner level regulation and is partic. for road vehicles. It has an oil-filled work cylinder under the pressure of a gas cushion acting as a spring arranged in a high pressure chamber. The cylinder is divided into two work chambers by a work piston supported by a hollow piston rod. The work cylinder is coaxially surrounded by a tubular component part (15), the angled end of which divides a high pressure chamber from a low pressure chamber. The tubular component part is of plastics and has a metal core (27). A suction tube (26) made of metal connects the low pressure chamber with the hollow pump rod.
